SITTING ON THE IRON THRONE Rhaenyra vs. Aegon

HOUSE OF THE DRAGON S03E08 - "The Treasons Of Tumbleton"

Okay but, as a professional historian, history is a bunch of competing narratives, sure, but some of those are still vastly more likely than others, and even though pure historical truth is forever out of our reach, your job is still to take a stance and, crucially, defend it. With evidence. And logic. Some sources are more reliable than others. And some events simply cannot be argued with due to their very public nature. So when F&B gives us different versions of a story, it's up to the writers to determine the most likely one based on the reliability of the sources and the inworld logic, not just pick the one they think would look "coolest". And that still leaves the instances where what F&B says is simply what happened, without a shadow of a doubt. Those things should not be changed. And any changes they DO make should make sense within the established rules of the universe.

Examples:

Aemond and Vhagar killing Lucerys by accident? Perfectly acceptable. We only know the outcome, we were not there in the sky with them, so it very well could have happened.

But Daemon being the one to kill Vaemond with no input from Rhaenyra? Simply not canon, because Rhaenyra feeding him to Syrax was a matter of public record at the time that no maester could conceivably later erase without a bunch of people going "wait, my dad was there when the Velaryons came to court to demand justice for it". Therefore, the show should not have changed that simply to make Rhaenyra more palatable.

Criston beating Joffrey to death instead of killing him in a tourney? Defies in universe logic, because a Kingsguard breaking guest right and committing murder during a wedding would have been executed.
